` IMPROVEMENT IN PIPE-COUELING-S.

The Schedule referred toin these Letters Patent and making part of the same 1b, a-Zi whom 'it 'may concerne` i Be it known `that I, LEONARD W. REED, vof East Cambridge, in the county` of Middlesex, and State o'f Massachusetts, `have invented certain new and useful `Improvements in Pipe-Couplings; and do hereby dev clare that the following is a full, clear, and exact description of the same, reference beinghad `to the accompanying drawings, makingapart of ythis specication, iniwhich- 1 Figure 1 isaside elevationof my improved device; Figure .Z'is a vvertical longitudinal section of Ithe Figure `3 is a securing together the sections of the coupling.

Letters of ,like name and kind refer to like'parts in each of the gures.

lMy invention relates to a class of devices used for seclring or coupling together the ends of metal pipes; an( f It consists in the employment of a coupling, composed of two sections, constructed and secured together `iu the manner hereinafter described, :so `as to permit said sections to be readily conuectedtogether or separated, and also, to, allowof their relative adjustmenujso as to bring the vlongitudinal openings therein in alliue with o'r at any desired angle to each In the annexed' drawing is shown a coupling, consistingof two sections, A and B, havingfin its centre, lengthwise,'af'liollow globe or sphere, C and G', which is divided throughits cutre, and the line of the division placed" atan auglevwit'h or'diagcnally to the longitudinal opening throughsaid coupling.

Projecting' forward from the outer edge of vone part saidsphere C, is an angular lip or ange, c, which tits into a corresponding groove in the opposite part C,'aud holds said parts inl positionlaterally, while detached view of the ring-clamp, for* allowing either to be rotated upon or separated trom the other.

The contiguous Vedges of the parts C and C being ground together so as to produce a steam or watertight joint, the whole is iirml y bound together by means of a ring, D, passing around the sphere, and providedwith a thumb-screw, E, which passes through said ring, and bears against one side or part of said sphere.

' 1n order that the clamps may bemore readily adjusted in place, with the pressure applied directly over the centre, radially of each half of the sphere, two bosses ma: are east at'that point uponrsaid halves, and are each provided with a conical countersink, for receiving the pointed ends of the screw E, aild of a pin,

(l, projecting inward, from opposite side of the ring D. r

Asth'us constructed, it will be seen that the sections of the coupling can be readily and Ifirmly secured together, or as quickly separated, and l that .from the construction and application of the clamp, it will be impossible for it to' become loosened by the jarring or motion of machinery, and also, that by rotating one portion of the Asphere upon the'other, the relative positions of the sections will` be changed, so as to produce au elbow-cbupliug, having any desired angle.

Having `thus fully set forth the nature and merits of my improvement,

What I claim as new, and desire to secure by Letters Patent, is-

The within-desc1-ibed adjustable coupling, consist-` ing of the sections A and B, secured together by means of the clamp-ring l) and screw E, substantially as and for the. purpose specified. A
